2005 Washington Revised Code RCW 59.18.140: Reasonable obligations or restrictions — Tenant\'s duty to conform.

The tenant shall conform to all reasonable obligations or restrictions, whether denominated by the landlord as rules, rental agreement, rent, or otherwise, concerning the use, occupation, and maintenance of his dwelling unit, appurtenances thereto, and the property of which the dwelling unit is a part if such obligations and restrictions are not in violation of any of the terms of this chapter and are not otherwise contrary to law, and if such obligations and restrictions are brought to the attention of the tenant at the time of his initial occupancy of the dwelling unit and thus become part of the rental agreement. Except for termination of tenancy, after thirty days written notice to each affected tenant, a new rule of tenancy including a change in the amount of rent may become effective upon completion of the term of the rental agreement or sooner upon mutual consent.
